Description

Düsenkrümmerausbauwagen Es sind Düsenkrümmerausbauwagen mit zwei hydraulischen Zylindern vorgeschlagen worden, die den Nachteil aufweisen, daß diese Zylinder durch kommunizierend wirkende Druckrohrleitungen verbunden sind, so daß eine außermittig aufgelegte Last die Gleitführungen zwischen Gestell und Hubrahmen verklemmen kann. Für die zur Anwendung kommende Handpreßpumpe gibt es keine wirtschaftlich durchführbare Lösung, beiden Druckzylindern genau die gleiche Ölmenge zwangläufig unterteilt zuzuleiten, damit beide Teile des Hubrahmens horizontal angehoben werden.Nozzle manifold removal wagons There are nozzle elbow removal wagons with two hydraulic ones Cylinders have been proposed, which have the disadvantage that these cylinders by communicating pressure pipes are connected, so that one off-center applied load can jam the sliding guides between the frame and the lifting frame. There is no economically feasible one for the hand press pump used Solution, to feed exactly the same amount of oil to both pressure cylinders inevitably divided, so that both parts of the lifting frame are lifted horizontally.

Der Erfindung liegt die Aufgabe zugrunde, bei Düsenkrümmerausbauwagen mit hydraulischem Hub den Hubrahmen unter Zwang horizontal anzuheben. Aus diesem Grunde wird erfindungsgemäß ein Hebelsystem in den Düsenkrümmerausbauwagen eingeführt, durch welches beide Seiten des Hubrahmens und demzufolge beide Zylinder genau den gleichen Hubweg ausführen müssen, unabhängig von einer einseitigen Belastung oder ungleichen Ölverteilung.The invention is based on the object of nozzle manifold dismantling cars to lift the lifting frame horizontally with a hydraulic lift. For this Basically, according to the invention, a lever system is introduced into the nozzle manifold removal car, by which both sides of the lifting frame and consequently both cylinders exactly the must perform the same stroke, regardless of a one-sided load or unequal oil distribution.

Der Erfindungsgedanke wird in den A b b. 1 und 2 dargestellt, die im folgenden beschrieben sind.The idea of the invention is shown in A b b. 1 and 2 shown, the are described below.

Zur Sicherung des Gleichlaufes der beiden hydraulischen Zylinder 6 wird erfindungsgemäß ein einfaches Hebelsystem vorgesehen, bestehend aus zwei Laschen 25, die mit ihren Drehpunkten 26 beiderseits am Fahrgestell des Wagens aasgelenkt sind, während sie mit den beiden Drehpunkten 27 an zwei Hebeln 28 aasgelenkt sind, die miteinander starr durch das Rohr 29 verbunden sind. Das Rohr 29 mit den beiden Hebeln 28 ist drehbar mittels Zapfen und Bohrungen 30 gelagert. Diese befinden sich in zwei äsen, die an dem U-förmigen Tragrahmen 4 für den Düsenkrümmer 18 befestigt sind. Diese Bauteile des Wagens heben den Düsenkrümmer an und senken ihn ab und zwar zufolge des Hebelsystems trotz der hydraulisch kommunizierend verbundenen Hubzylinder zwangläufig senkrecht zur Standfläche des Wagens bzw. parallel zur Laufachse.To ensure that the two hydraulic cylinders 6 a simple lever system is provided according to the invention, consisting of two tabs 25, which aasgelenken with their pivot points 26 on both sides on the chassis of the car are, while they are articulated with the two pivot points 27 on two levers 28, which are rigidly connected to one another by the pipe 29. The tube 29 with the two Lever 28 is rotatably mounted by means of pins and bores 30. These are located in two axes, which are attached to the U-shaped support frame 4 for the nozzle manifold 18 are. These components of the car raise and lower the nozzle manifold and due to the lever system despite the hydraulically communicating lifting cylinders necessarily perpendicular to the base of the car or parallel to the axis of the barrel.

Für den gemeinsamen Transport von Düsenspitze 19 und Düsenkrümmer 18 mit dem Düsenkrümmerausbauwagen ist zur Verbindung beider Teile eine an sich bekannte Spannschloßverbindung 22, 23, 24 vorgesehen.For the joint transport of nozzle tip 19 and nozzle manifold 18 with the nozzle manifold extension car is one in itself to connect the two parts known turnbuckle connection 22, 23, 24 is provided.
